  • Patent number: 4231400
    Abstract: The removable two-way connector is designed for faucets with a nozzle for feeding auxiliary apparatus, such as shower heads, massage devices and the like. It comprises a body with an annular wall divided into four segments and defining a cavity in which a deformable packing sleeve is disposed. The wall has a peripheral wall forming a spiral camming face at each wall segment. A rotary cover caps the cavity and has radially inwardly extending ribs with cam follower faces engaging the spiral camming faces. When the cover is turned, the wall segments are forced radially inwardly by the displacement of the cover ribs along the camming faces whereby the inwardly forced wall segments are pressed against the adjacent deformable sleeve and the sleeve sealingly engages a nozzle surrounded thereby.

  • Patent number: 4213573
    Abstract: A bobbin revolver for winding textile filaments has a rotatable chuck carrier with a plurality of bobbin chucks. The carrier is rotatable on a central shaft to urge the chucks successively towards a friction drive drum which rotates bobbins on the chucks to wind filament packages thereon. A fluid coupling, comprising co-axial, relatively rotable parts having communicating passages therethrough, is provided around the shaft to pass pressure fluid to and/or from devices on the carrier. The fluid coupling is arranged so that there is no relative rotation of its parts during winding of a package, thereby avoiding disturbance of the contact pressure between a package and the friction drum through sliding friction between the coupling parts.

  • Patent number: 4117856
    Abstract: A backflow preventer in a fluid conduit permits flow from the inlet to the outlet of the preventer when the inlet is pressurized and prevents reverse flow upon termination of flow through the preventer. An apertured diaphragm between the inlet and outlet closes a valve seat between the outlet and a vent passage when the inlet is relatively pressurized. A check member upstream of the diaphragm closes the diaphragm aperture if the outlet is relatively pressurized and maintains the diaphragm aperture closed upon pressurization of the inlet until after closing of the vent valve seat. A second vent communicates with the interior of the preventer and is closed by a portion of the diaphragm upon pressurization of the interior. A relief port in the chamber includes a temperature responsive element that opens the relief port once ambient temperature reaches a preselected level. The inlet includes an internally threaded sleeve within the housing that may be secured to an externally threaded fluid hydrant.
